Abstract
Methods of forming a laminate may include conveying a first substrate through a first nip, where a first source of vibration energy may be used to alter a portion of the first substrate in the first nip to create an altered area. The method may include conveying the first substrate with the altered area and a second substrate into a second nip and using a second source of vibration energy to join the first substrate to the second substrate in the second nip.
Claims20
A method of forming a laminate comprising:
- providing a first device comprising an outer surface;
- providing a second device comprising a first source of vibration energy;
- forming a first nip between the first source of vibration energy and the outer surface;
- conveying a first substrate through the first nip;
- using the first source of vibration energy to alter a portion of the first substrate in the first nip to create an altered area;
- providing a third device comprising a second source of vibration energy;
- forming a second nip between the second source of vibration energy and the outer surface;
- wherein the second nip is downstream of the first nip;
- conveying the first substrate with the altered area and a second substrate into the second nip;
- and
- using the second source of vibration energy to join the first substrate to the second substrate in the second nip.

- providing a second device comprising a first source of vibration energy;
- forming a first nip between the first source of vibration energy and the outer surface;
- conveying a first substrate through the first nip;
- using the first source of vibration energy to alter a portion of a machine directional lane of the first substrate in the first nip to create an altered area;
- providing a third device comprising a second source of vibration energy;
- forming a second nip between the second source of vibration energy and the outer surface;
- wherein the second nip is downstream of the first nip;
- conveying the first substrate with the altered area and a second substrate into the second nip, wherein the first substrate has a first cross-directional width, wherein the second substrate has a second cross-directional width, and wherein the second cross-directional width is larger than the first cross-directional width;
- and
- using the second source of vibration energy to join the first substrate to the second substrate in the second nip.
